I confess I don't understand this program. I installed it on my laptop because I find my laptop invariably too bright. Now it's just as bright... but sort of pinkish. Does pinkish help? Because it just looks like my monitor wants me to donate to breast cancer research right now.

Pinkish decreases contrast. But everyone has personal preference. It may look good to me, but not to others.

If you are using the Windows version, there should be an icon down in the notification area by the clock. Right-click that to access the options, including turning it off, stopping it from starting with Windows, or turning it off for an hour (if you needed to work with accurate color for a bit, for example).

I came across this program and like it very much. It changes the "color temperature" of your display to better approximate natural sunlight. You can control how much, and how fast, it changes. Windows, Mac, IOS, and Linux versions, and an Android version in progress.

The main reason I think it is good is there is substantial evidence that blue-rich light keeps us awake at night and affects our internal "clock". You can read more about it on the site, under the "Sleep Research" and FAQ pages, and decide for yourself.

For people who might want to sleep a little easier after reading (or surfing) at night: this might help.
